Support IUsb AIDL interface

UsbPortManager is made to support both AIDL & HIDL interface until
HIDL is deprecated eventually. UsbPortHal abstract class is defined
which the UsbPortManager grabs an instance of from UsbPortHalInstance
method to talk to the Hal implementation process. UsbPortHalInstance
queries the underlying hal implementation and instantiates UsbPortHal
with either UsbPortHidl or UsbPortAidl based on the IUsb interface
implemented by HAL implementation.
